<p>Red teams usually consist of ethical hackers, penetration testers and other security professionals. To be effective, red team members should have no knowledge of an enterprise’s defense mechanisms. As such, organizations often outsource red team services to a third party.</p>
<p>During cybersecurity exercises, red teams use <a href=”https://www.techtarget.com/searchsecurity/tip/6-common-types-of-cyber-attacks-and-how-to-prevent-them”>real-world cyberattack techniques</a> to act as adversaries that exploit weaknesses in a company’s people, processes and technologies. Common techniques include the following:</p>
<ul class=”default-list”>
<li>Penetration testing.</li>
<li>Phishing and social engineering.</li>
<li>Credential theft.</li>
<li>Port scanning.</li>
<li>Vulnerability scanning.</li>
</ul>
<p>Team members use open source, commercial and custom-made tools to infiltrate systems and then escalate privileges to successfully “breach” the network.</p>
<p>Post-attack reporting is another red team task. Members write up de
